I remember buying a pair of limited edition gunmetal Hyperions which looked gorgeous and I recall thinking that they sounded really good; astonishingly good for their size and price; hugely enjoyable, dynamic, v-shaped, powerful and terrific fun.
At that time, I think I already had owned IEM's costing £140+.
Someone borrowed and lost them, so about a year or so later I emailed TA and asked if they had any they could sell me another pair during the early-mid stages of the TA meltdown (I think they were not listed on the website at that time, but the rep said they had one or two and could sell to me).
I hadn't heard them in ages, but remembered being shocked at how cheap and crappy they sounded. Ended up chucking them out I think.
So I wondered whether my tastes had just matured with exposure to higher-end IEM's (I think I owned the flagship Noble Audio Katana by then)?
But then, I still love my $89 iBasso IT01. Knowing what I know now, I suspect I was sold a unit that was defective, or built with an inferior quality driver inside?
Not sure, but your praise of the Hyperion gives further weight to my suspicions!
If anyone has a good Hyperion they'd be willing to give/sell/trade me, please PM me; dying to get another pair. Even more so if they're the gunmetal model - I love that colour
